Input type file accepts MS presentations

In html5, input tag has a property called accept to filter the kind of files. If we want to filter just power point files, we should do something like as follow:

	<input id="media-file-upload"
	class="input-upload"
	type="file"
	nv-file-select=""
	uploader="mediaListCtrl.uploader"
	accept="application/vnd.ms-powerpoint,
	application/vnd.openxmlformats-officedocument.presentationml.slideshow,
	application/vnd.openxmlformats-officedocument.presentationml.presentation"
	multiple/>

With this, we are filtering .ppt, pptx and ppsx

But there is a trick xD
Look at the next screenshot:

Easy, right?

Happy coding! :)
